Get a thudbuster. There's no reason not to, and there's no reason to buy anything else. Set up properly it WILL make your ride very noticeably more plush. Wont make you faster, but it will give you more comfort and more control and downhills that you had to stand for before that you can now sit on.archer said:
I have a rockshock with a long red elastomer in it tightened up so there is very little sag...i dont like the downside of sag...when you are behind saddle on steep descent and need to come forward for a log or rock...lol. I am nearly 200lbs so it still takes the big hits esp when climbing...i dont have to come out of the saddle as much.CharT said:The USE is practically the same weight as most stock seatposts and travels in a straight line. The Thudbusters are heavier and travel in an arc. If you have a preference to the way your saddle is going to move about while you pedal, you should try them out first to make sure you don't get annoyed by the motion of the suspension seatpost. I have the original USE shokpost ordered from England about 7 years ago. It's never let me down and I'm able to stay seated and pedal over a lot of stuff when my friends need to stand. I hear the XCR works even better and has more travel. However, you need to be realistic about it and know that suspension seatposts are not going to give you a super smooth ride. They take some of the bumps out, but you essentially end up with a rear suspension that has a virtual pivot about the handlebars or somewhere up in that area.
Three years ago, it was either buy a F/S or quit riding. My lower back was killing me for a week after every ride. I did a bunch of research, tried various brands of suspension seatposts, and bought a ThudBuster. The four-bar set-up is much better than a linear movement because it doesn't affect your pedal/saddle geometry much if at all. Sure, the rearward arc affects fore/aft position, but that's not as crucial.archer said:
I got a Rock Shox sus seatpost about 2 years ago after reading all the reviews here in an attempt to relieve a very strong lower back pain I would get around few tracks I race on.archer said:
Very true! This can also happen on a full suspension bike if you stay seated taking a harsh hit. When I got my first full suspension, I made the assumption that I could sit through absolutely everything, even drops. Hey I was young and dumb! Took a 1 foot drop at full speed the bike bucked me on the rebound. I quickly learned.Boj said:...As for all those people who got projected OTB - It's not the suspension post that's launching you, its you attempting to sit while riding harsh bumps just like you would get thrown when riding any rigid pos...
